XML to HTML converter.

[somnathbanik]

Hi,

I got this open source lib to display the UI components on the screen using html tags.

http://code.google.com/p/htmlcontrol-for-symbian/

I used the Form example and was able to see the UI on the screen. Even I could change the html tags and modify the UI components. But is there any other open source lib that can generate UI using the xml tags as it is doing here, or is there any way I could change the xml tags to html tags, so that I could use this .

Please suggest me.

There were rumors about a forthcoming XML-based UI for Symbian/S60, but the project is likely dumped in favour of Qt.
Anyway, note that HTML is a far less strict format than XML, so depending on your XML format, renaming the tags may already turn out to be enough.

Is there any way I could replace the xml string to html string.
eg. <tablerow> ---> <tr>

kind of file read/write program.

I would do that using descriptors.

[somnathbanik]

descriptors? How, using HBufC/ TBuf.

Please suggest me with some code.

Yes, that is exceptionally hard.

_LIT(KSomething,"blablabla<tablerow>blablabal</tablerow><tablerow>blablabla</tablerow><tablerow/>");
TBuf<200> buf;
buf=KSomething;

_LIT(KFind1,"<tablerow");
_LIT(KReplace1,"<tr");

TInt pos=buf.Find(KFind1);
while(pos>KErrNotFound)
{
    buf.Replace(pos,KFind1().Length(),KReplace1);
    pos=buf.Find(KFind1);
}

_LIT(KFind2,"</tablerow");
_LIT(KReplace2,"</tr");

pos=buf.Find(KFind2);
while(pos>KErrNotFound)
{
    buf.Replace(pos,KFind2().Length(),KReplace2);
    pos=buf.Find(KFind2);
}

Of course I am cheating, because 'tr' is shorter than 'tablerow'. Replacing something with a longer text would require dynamic memory allocation, like HBufC-s or CBufFlat-s.

After replacing the string from KSomething, where the replaced string will be stored. in buf?

I am trying to display the replaced sting but getting an error message Panic KERN-EXEC 3

here is my code

case EHelp:
			{

			_LIT(KSomething,"blablabla<tablerow>blablabal</tablerow><tablerow>blablabla</tablerow><tablerow/>");
			TBuf<200> buf;
			buf=KSomething;

			_LIT(KFind1,"<tablerow");
			_LIT(KReplace1,"<tr");

			TInt pos=buf.Find(KFind1);
			while(pos>KErrNotFound)
			{
			    buf.Replace(pos,KFind1().Length(),KReplace1);
			    pos=buf.Find(KFind1);
			}

			_LIT(KFind2,"</tablerow");
			_LIT(KReplace2,"</tr");

			pos=buf.Find(KFind2);
			while(pos>KErrNotFound)
			{
			    buf.Replace(pos,KFind2().Length(),KReplace2);
			    pos=buf.Find(KFind2);
			}
			  _LIT(KMenuItem,"%S");
			  TBuf<201> buf1;
			  buf1.Format(KMenuItem(), buf);       
			  CAknInformationNote* info = new (ELeave) CAknInformationNote;
			  info->ExecuteLD(buf1);
			        	        	        
			}
			break;

please sugges me.

Yes I have solved it.

here is the code

	case EHelp:
			{

			_LIT(KSomething,"blablabla<tablerow>blablabal</tablerow><tablerow>blablabla</tablerow><tablerow/>");
			TBuf<200> buf;
			buf=KSomething;

			_LIT(KFind1,"<tablerow");
			_LIT(KReplace1,"<tr");

			TInt pos=buf.Find(KFind1);
			while(pos>KErrNotFound)
			{
			    buf.Replace(pos,KFind1().Length(),KReplace1);
			    pos=buf.Find(KFind1);
			}

			_LIT(KFind2,"</tablerow");
			_LIT(KReplace2,"</tr");

			pos=buf.Find(KFind2);
			while(pos>KErrNotFound)
			{
			    buf.Replace(pos,KFind2().Length(),KReplace2);
			    pos=buf.Find(KFind2);
			}
			
			     
			  CAknInformationNote* info = new (ELeave) CAknInformationNote;
			  info->ExecuteLD(buf);
			  
			        	        	        
			}
			break;

Just for future reference: %S expects the address of a descriptor, not the descriptor itself:

_LIT(KMenuItem,"%S");
TBuf<201> buf1;
buf1.Format(KMenuItem(), &buf);
